Avalanche
Several unsuspecting children were sledding on an avalanche-prone slope in Turkey when the things turned for the worst and they triggered a massive avalanche.
Three of the children went down at once and everything seemed fine until they neared the bottom of the slope. Then the whole face went all at once and a waterfall of snow erupted down the hill.
Miraculously, none of the children were buried and no one was injured. Apart from being utterly terrified, they got extremely lucky.
